TREATING AILMENTS OF YOUNG CATTLE 307 



a specific organism (bacteria), which finds its way into 

 the blood either through the navel or the mouth. In 

 bad cases, the calf's eyes appear sunken about the 

 second or third day after the attack. It takes very 

 little food, commences scouring, and probably dies next 

 day. The end is so sudden that there is not much hope 

 of saving its life when the disease has once got a hold. 

 Remedies are not of much avail in this case, the great 

 thing is prevention on the following lines : 



1. The calf box should be cleaned out and 



thoroughly disinfected before admission of 

 calves in spring, and at subsequent periods of 

 two or three months. The floor should be 

 well dusted with powdered lime, and the walls 

 lime-washed. The lime-wash should have some 

 carbolic added. Clean litter may then be 

 placed on the floor to make a comfortable bed 

 for the calf. 



2. The calf box must be well lighted and well 



ventilated, so as to assist in the destruction of 

 disease germs. The best arrangement is to 

 have window-ventilators, which are hinged 

 along the bottom. The window then opens 

 inwards and guides the incoming air against 

 the roof before it is reflected on the calves. 



These two preventions were sufficient in 

 the writer's experience to rid the disease out 

 of a dark, unventilated calf box, which was a 

 veritable death-trap for calves introduced into 

 it. But two or three other precautions may 

 be taken : 



3. Disinfect the navel of the calf with a 2 per cent. 



solution of lysol at birth.
